"HomeRx’s sales rep, Bryant, came to assess the attic and crawl space in an older home I purchased. His kind, calm manner of explaining what I needed and how HomeRx would remediate it was reassuring. He told me HomeRx and Energy Trust of Oregon are in a partnership. When I learned I qualified for an ETO rebate, it was so much more generous than I’d expected! HomeRx’s expertise, along with their care, flowed from beginning to end. When I called/visited the office, I felt truly valued as a customer. Alma, Taylor, Samual, Jennifer, Kimberly, and Adan each explained what I needed to know from their unique area of expertise! If there was a glitch, it was fixed to their standards. When I met Jose, HomeRx president, I felt his leadership had a genuinely heartfelt foundation, whether it was in his care for me, his customer, or in his manner of relating with his HomeRx’s teams. I highly recommend HomeRx for any service they offer that meets your needs. You can’t go wrong."

"I called asking for service at 1:00PM and John fixed the problem by 6:00PM. Five hours from first contact to job complete is pretty impressive. John did a quality job. He quoted the cost and explained clearly what would be done. He also didn't upsell which was great. I would highly recommend this company for any garage door need."

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Energy Efficiency Auditing FAQs, answered by experts

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.
